Possibility of large span at equal load or high load bearing capacity at an equal span. But the use will always be very limited due to reduced resistances towards shear, local punching and fire.
Although not reinforced, bubblddeck were used to reduce the weight.

Double slab, upper and lower. Reduction of columns section or their number. Designing is consequently like for solid slabs, but with less load corresponding to the reduced amount of concrete. The soffit has a flat surface that is ready to finish and does not require a false ceiling for aesthetic purposes.
Voided biaxial slab – Wikipedia
February Learn how and when to remove this template message. A two way spanning biaxial slab construction compared to a one way spanning deck traditionally a hollow core:. All tested buildings are proven safe, and are reopened. BubbleDeck is a biaxial technology that increases span lengths and makes floors thinner by reducing the weight while maintaining the bbubbledeck of reinforced concrete slabs.

In practice, the reduced shear resistance will not lead to problems, as balls are simply left out where the shear is high, at columns and walls. Statements consisting only of original research should tecynology removed. Other types of voided biaxial slabs have reduced resistances towards shear, local punching and fire. Can bubbledecck used together with prefabs. Due to the specific shape of the voids, there are no issues with internal pressure.
Savings in useful height on each level as there are no emerging beams. Can’t get enough TreeHugger? Reduction in the number of pillars. The dollar store is America’s new invasive species. Regardless of project size, shape or complexity; simply shore, place, and pour to quickly install concrete decks. Moreover,the slab will not explode due to the escaping of over pressurised gas from the feet 4 feet for each formwork that act as safety valves.
Flexible Span up to 20 m.
Please improve it by verifying the claims made and adding inline citations. Email Address Email is required.
For this reason major developments of reinforced concrete have focused on enhancing the span, either by reducing the weight or overcoming concrete’s natural weakness in tension. This section possibly contains original research. Cement, the Unheralded Polluter.
Economical and technolpgy to transport, handle and store, also outdoors. Views Read Edit View history. Daily and Weekly newsletters available.
BubbleDeck – the Biaxial Hollow Deck
While concrete has been used for thousands of years, the use of reinforced concrete is usually attributed to Joseph-Louis Lambot in The idea of placing large blocks of light material in the slab suffers from the same flaws, which is why the use of these systems has never gained acceptance and they are only used in a limited number of projects in Spanish-speaking countries. Fewer dimensional limitations for the elements.
All advice, information and software from this site are intended for those who will evaluate the significance and limitations of its contents and take responsibility for its use and application. The voids are positioned in the middle of the cross section, where concrete has limited effect, while maintaining solid sections in top and bottom where high stresses can exist. The splice bars are inserted loose above the pre-cast concrete layer between the bubbles, and purpose made mesh sheets tied across the top reinforcement mesh to join the elements together.
Voided biaxial slab
Once concrete is poured over the balls in the panels, the BubbleDeck system effectively becomes, technologgy behaves like, a monolithic two-way slab that distributes force uniformly and continuously. The overall floor area can be divided down into a series of planned individual elements, up to 3 m wide dependent upon site access, which are manufactured off-site using MMC techniques.
The voided biaxial slabs technology is directly incorporated in international standards as the Eurocodes, and various national codes such as the CUR in the Netherlands.
The fire resistance is dependent on the temperature in the rebars and hence the transport of heat. Voided biaxial slabs are reinforced concrete slabs in which voids reduce the amount of concrete.

This small apartment building in Seattle could be a model for solving our housing and energy crises.

An early example is the Pantheon in Romebuilt AD.
